Collapsible lattice type "mail"

Collapsible lattice type "mail" is intended for decorative overlapping openings of Windows and doors protected areas and institutions. It consists of modules with hooks placed rows and oriented perpendicular to the rows area. What's new is that the modules are made of rods in the form of a trapezoid, and the hooks open. New is the module itself, in which the height of the line exceeds its base, and hooks made in the form of 0,7-0,8 coil, the diameter of which exceeds the transverse dimension of the rod, when this coil is located above the plane in which is placed the keystone. Module option differs in that its upper portion bent relative to the plane at an angle of 10-20 degrees. 2 C.p. f-crystals, 4 Il.

The invention relates to the field of folding grilles and is intended for protection of Windows and doors by closing openings with decorative grilles from penetration.

Known folding of the lattice in the form of wire meshes containing ring elements, woven honey a [1]The closest known lattices is foldable grill, which contains comparative elements (modules) with two hooks at snowm series direction. Moreover, adjacent modules attached neighbors hooks on the upper part of the lower module.

The disadvantages of the known folding grids (grids) should include the inconvenience of folding, which consists in folding the grid, as well as the lack of ornamentality of such arrays.

The aim of the invention is to remedy these disadvantages.

The aim is achieved in that in the known folding lattice modules made of rods in the form of a trapezoid without reason, and the line have a spatial shape by bending it in the plane of arrangement. When the hooks are made open, vneshnemembrannye.

The module proposed collapsible lattice type "mail", contains a link from a rod in the form of broken trapeliopsis line connected at the lower ends of the lateral sides with connecting elements in the form of vneshneporozhdaemyh closed hooks differs in that the link is made with a height greater than the distance between the lower ends of the lateral sides, and each connecting element is designed in the form of 0.7 - 0.8 of a coil, the diameter of which exceeds the transverse dimension of the cross section of the beam at this stage of the connecting element is located above the plane in which is placed Blige the x2">Development is the module in which part of the link, which forms the smaller base of the trapezoid, and part of the adjacent sides are angled relative to the plane of the link at an angle of 10-30o.

The invention is illustrated by drawings, where Fig.1 shows the lattice of type "mail", General view, Fig.2 module, front view, Fig.3 module, side view, Fig.4 a variant of the filling module.

Collapsible lattice type "mail" contains modules 1, each of which has a trapezoidal shape. The grating is fixed between the parallel bars 2. The module has a smaller base 3 and side 4. The sides are made with 4 hooks 5, which represents the partial coils located on one side of the module 1. The hooks 5 are fixed on smaller bases 3 adjacent modules 1. When approaching strips 2 modules 1 going into an accordion. Modules 1 turn hooks 5 at the lower base 3. Module 1 can be performed with a part forming a lower base 3, and part of the sides 4, curved relative to the plane of the module 1 at an angle of 10-30o.

Module 1 can be performed by a height greater than the distance between the lower ends of the side walls 4. Each hook 5 is made in ologen above the plane hosting the plot polylines trapezoidal module 5. Straight section of the hook 5 is placed under the plane.

As blanks module 1 uses a rod with a diameter of 8-10 mm from metal, for example stainless steel. The modules 1 are manufactured using bending machines or devices. After this folding grille is assembled from modules 1 through donning zalivochnym movement of the upper module 1 on the bottom.

1. Collapsible lattice type "mail" containing trapezoidal modules with open hooks at the bottom of the base, characterized in that the modules are in the form of spatial figures, and the hooks are vneshnemembrannye and directed along the line of the lower base of the trapezoidal module.

2. The bars on p. 1, characterized in that the module is made of a height greater than the distance between the lower ends of the lateral sides, and each hook is made in the form 0,7 0,8 coil, the diameter of which exceeds the transverse dimension of the cross section of the rod at the top of the module, with round toe is located above the plane which contains the plot polylines keystone module, and the straight section of the hook below this plane.

3. The bars on p. 1, wherein those who Scotti link angle, equal to 10 30o.
